I had a bone marrow transplant and was an “in-out patient” or whatever they called it for two months. I stayed in a residential apartment owned by the hospital for two months. I had appointments everyday. Depending on my labs, I’d get whatever transfusion I needed. My daily appts we’re anywhere from 1 hour to 5. Staying in the residential apartment meant not staying in a hospital room with whatever lights. I was able to cook food with my car giver and feel somewhat normal. And I just walked over to my appt each day. I also walked rounds around the hospital to get steps in.

One taken for granted benefit was the air filtration. Air was supposedly sucked out of the building to help those (most) of us who were immunocompromised. If it’s just you living in the van I don’t think it’s an issue. I’d it were me, I’d be concerned about how clean things were.
